Actor Jim Broadbent has reportedly signed up to the HBO series to fill a ‘significant’ role for season seven and it’s got fans pretty excited.

It’s hard to imagine Harry Potter’s Horace Slughorn in the unforgiving world of Westeros, but Entertainment Weekly have reported that he is indeed on board.

That, however, is pretty much it. There’s no news on his character, whether he’s good or bad, or even where his alliances will lie.

All we do know is that the new series, which will consist of just seven episodes, will be filmed in Northern Ireland, Spain and Iceland, so he’ll probably be hanging around those places.

Jim played Horace in two of the films from the Harry Potter franchise, and most recently reprised his role as Bridget Jones’ dad in the film Bridget Jones’ Baby, starring alongside Renee Zellweger and Colin Firth.

Fans are now speculating what will be in store for him in Westeros, given that he’s mainly only played nice characters:
